MySQL LOCALTIMESTAMP or Localtimestamp() are the two Date Functions, used to return the current date & time in YYYY-MM-DD HH:MM:SS.
MySQL LOCALTIMESTAMP Syntax
The basic syntax of the local timestamp in MySQL is as shown below:
LOCALTIMESTAMP;
LOCALTIMESTAMP();
TIP: Both these local timestamp functions are the synonyms of the NOW function. All these three functions return the same output.
MySQL LOCALTIMESTAMP Example
The following statements show you how to use these MySQL local timestamp functions.
SELECT LOCALTIMESTAMP;
SELECT LOCALTIMESTAMP();
SELECT NOW();
OUTPUT
As you can see from the above, the three statements return the local date and time stamp in YYYY-MM-DD HH:MM:SS format.
The below statements show what happens when adding a few seconds or random value to the MySQL localtimestamp() function.
SELECT LOCALTIMESTAMP, LOCALTIMESTAMP + 22;
SELECT LOCALTIMESTAMP(), LOCALTIMESTAMP() + 15;
SELECT DATEDIFF(LOCALTIMESTAMP(), '2019-01-01');
OUTPUT
From the above screenshot, you can see the function added those extra seconds and displaying the date in YYYYMMDDHHMMSS string format
Within the last statement, we used the Datediff function to find the difference between the local timestamp and the custom date ‘2019-01-01.’
